Needle-Free Targeted Injections Using Bubble Laser Technology in Therapeutics

Langmuir, Год журнала: 2024, Номер 40(44), С. 23549 - 23561

This work explores bubble laser technology as an alternative to needles in injection systems for vaccination, cancer treatment, insulin delivery, and catheter hygiene. The leverages laser-induced microfiltration dynamics create high-speed pneumatic jets that penetrate the skin without needles, addressing discomfort, infection risk, needle-related concerns. system's performance is analyzed based on wavelength, pulse duration, Gaussian beam droplet size. findings indicate a significant increase spot size at 1064 nm compared with 400 nm, consistent diffraction theory. Induced reveal generation, jetting, fluid interactions Weber number increases, well jet velocity inertia. For femtosecond pulses, increasing duration from 100 1500 fs reduces lifespan 0.8 0.3 arbitrary units, collapse pressure decreases 2.1 0.4 bar. picosecond lifetime 0.9 0.5 drop 2.0 bar length extends 2000 8000 ps. Jet formation enhanced by short pulses water produce longer-lasting bubbles. Drug delivery Rayleigh-Plesset equation characterized low-pressure lifetime. Thus, this relationship suggests can provide more controlled safer method of needle-free procedures, compliance reducing tissue trauma.
